Sandwich Osteotomy
Conditions
Brief summary
In conventional segmental sandwich osteotomy technique the moving the transport segment inferiorly to increase the vertical height causes the segment to move bucco-palatally, increasing the horizontal defect. So using the computer guided in segmental sandwich osteotomy and fixation the transport segment hopefully will reduce the bucco-palatal tipping.
Interventions
PROCEDUREcomputer guided sandwich osteotomy
segmental sandwich osteotomy will be done for vertically deficient ridges in anterior area of the maxilla. Either using surgical guides (Computer guide segmental sandwich osteotomy technique) for study group and conventional segmental sandwich osteotomy technique for control group.

Inclusion criteria
* Patients with vertically deficient anterior maxillary ridge a minimum 10 mm. height of alveolar bone. * Patients with medical history that did not hinder implant placement (uncontrolled diabetes) and adequate proper oral hygiene. * Patients of adequate alveolar bone width. * Both genders males and females will be included.
Exclusion criteria
* General contraindications to implant surgery. * Subjected to irradiation in the head and neck area less than 1 year before implantation. * Untreated periodontitis. * Poor oral hygiene and motivation. * Uncontrolled diabetes. * Pregnant or nursing. * Substance abuse. * Psychiatric problems or unrealistic expectations. * Severe bruxism or clenching. * Immunosuppressed or immunocompromised. * Treated or under treatment with intravenous amino-bisphosphonates. * Lack of opposite occluding dentition/prosthesis in the area intended for implant placement. * Active infection or severe inflammation in the area intended for implant placement. * Need of bone augmentation procedures at implant placement. * Unable to open mouth sufficiently to accommodate the surgical tooling. * Patients participating in other studies, if the present protocol could not be properly followed. * Referred only for implant placement or unable to attend a 5-year follow-up. * Requiring only single implant-supported crowns.
